It seems your shop script accept everything to upload also php, exe, js etc i would consider this as a big security hole,also when the files get a random string.
On celular screen it doesnt show all products from start page just 2 !! and this one are not correct responsive i recommend you include uikit in next version
I need some help to install this shop correct the exchange rate stay on 301.33 usd / BTC also cant found any tutorial or other instruction on how to install using default gataway from tor network (shop have .onion domain)
